Skype 8.x doesn't
support any API for developers
and we spent lots of efforts to
keep our Skype gateway functions. This time,
we will charge on
software upgrade for
products SkyATA(or
SkypeKey,
SkyTrunk and
HT44), SkyBox S1(or
Sky911, SkyPeBX and ST-1002)
, SkyGW4C-S and SkyGWO. For
customers who purchased these products within one year, they
will get a free software upgrade for Skype 8.x.We will release updated
software for our various Skype gateway products to support
most recent Skype version 8.30.0.50
and later on versions.

Voice quality of Skype 8.x is much better compared with that
of Skype 7.x. And recent Skype 8.x version can support audio/video
reccording and received files share is much convenient than
the 7.x version.
There are still partial functions of our Skype gateway
not
ready
and our customers can run Skype 7.x with our Skype
gateway devices
for
now. We plan to have
upated
Skype gateway
software for Skype 8.x
on
October 25.
